Thanks for fixing this. I am not a native English speaker and I make
mistakes. Either it is a grammar or convention mistake, I would
appreciate it if you point them out, so I could learn from them.
About the "start with an uppercase character", I actually on purpose
changed my approach some time ago after seeing more senior kernel
developers using this method (see commits from Linus Torvalds, Andrew
Morton). After the subsystem prefix "mfd: ...." they start with
lowercase. If you still insist that commit titles in MFD subsystem
should use capital letter after the prefix, I will try to remember and
follow this approach when sending patches to you.

Best regards,
Krzysztof
